SLED.

SPECIFICATION forming part of Letters Patent No. 349,827, dated September 28, 1886.

Application filed January 29, 1886. Serial No. 190,160. (No model.)

To @ZZ whom it may concern:

Bc it known that I, OTTO UNZICKER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sleds, of which the following is a specification, reference being had therein to the accompanying drawings.

The object I have in View is to produce a sled combining great strength with lightness, and that is neat and graceful in appearance.

For that purpose my invention mainly consists in forming the runners of cylindrical wooden rods, and in lining such runners with semicircular iron curvilinearly extended at both ends to connect with the raves and crossbars, also in round iron braces diagonally connecting the runners with the cross-bars of the sled, all as hereinafter more fully described and specifically claimed.

In the accompanying drawings, Figure l represents a perspective view of the sled, the seatboard being removed; Fig. 2, a vertical crosssection of the same; and Fig. 3, a sectional dctail showing the connection of a cross-bar, brace, and rave by a single bolt.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the runners, and B the raves, both being cylindrical wooden sticks.

C C are the cross-bars, the ends of which are connected by the raves I3. Upon these cross-bars C C the scat-board D is secured. The runners A are lined on their bottom with semicircularlyshaped iron bars E, extending at both ends beyond such runners, the forward extensions of bars E being curved upward and then to the rear, and their ends secured upon the front ends of raves B and their rearward extensions being curved up and forward, with their ends secured under the rear crossbar, C. A round iron brace, F, extends from each runner A diagonally to the under side of the opposite end of a cross-bar, C or C, in a manner that such cross-bar is thus connected with and supported on the two runners by two such braces F crossing each other. These cross-braces are bent at j, to provide a long bearingsurface for the cross-bars thereon, and thereby obtain additional strength. These cross-braces also have eyes formed to their ends, to be secured upon the runners A each by a rivet, a, passed through the ruimer A, bar E, and through such eye of brace F. To

each end of a cross-bar C C is rigidly con- O nected the end of a rave, B, of a bar, E, and a brace, F, by a single screw-bolt, b, passed through allthese parts. The curved front ends of bars E are connected by a chain, G, as a handle, or for connecting a rope by which to pull the sled. As will be readily seen, the bars E, forming the shoes for the runners, also brace the seat longitudinally, while the cross rods F not only form strong supports for the seat of the sled, but lateral braces as well for securely holding the runners in a proper paral lel position relative to such seat.

Cylindrical runners are cheaper to manufacture than when made any other shape, and their appearance is light and neat, while the semicircular bars inclosing their under surface will not only stiffen these runners to a great extent, but will also prevent their splitting with riveting.

l. In a sled, the combination, with cylindrical runners, of semicircular bars forming shoes for these runners, and having curved extensions that conncct with the raves and crossbars of the scat portion of the sled, substair tially as s'et forth.

2. In a sled, the combination of cylindrical runners, of semicircular bars forming shoes for these runners and having curved extensions that connect with the raves and crossbars, and of iron cross-rods connecting the runners with the cross-bars and acting as supports and braces thereto, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO UN ZICKER.
